Your Best Work May Already Be Training Someone Else’s AI — for Free

Your best work-those reports, internal docs, strategy decks, process docs, wikis, even Slack threads-may already be training someone else’s AI. And not only are you not getting paid… you probably don’t even know it’s happening.

On June 24, 2025, U.S. District Judge William Alsup ruled that Anthropic’s use of legally scanned books to train its Claude AI model is “transformative” and protected by fair use.

With Anthropic’s legal victory, the courts just handed AI companies a powerful precedent: using legally obtained books and documents to train AI models is “fair use.” This ruling opens the door wide-but it also forces a reckoning for professionals and business leaders.

If your knowledge is digitized, it’s valuable. And if it’s valuable, it’s monetizable. But right now, someone else might be monetizing it-without your knowledge, or your consent.

History Repeats: Previous Disruptions Are Telling Us What’s Coming

Anthropic’s landmark legal victory on the fair use of copyrighted works for AI training has captured the tech world’s attention. This ruling, while significant on its own, is a familiar echo of past technological evolutions I’ve witnessed over the years.

I operated on the front lines of multiple technology revolutions-distributed computing, the internet, open source, mobile, and cloud-and this moment feels very familiar. When I consider the looming struggle of our legal system to keep up with AI, I think back to similar struggles around things like digital copyrights (think Napster), the legality of digital signatures (think DocuSign), data sovereignty (think IaaS), and even determining sales tax on SaaS subscriptions.

Once again, legal frameworks are scrambling to catch up with technology. But this time, the stakes are higher: the very act of learning -digitally, at scale-has become a commercial concern.

History, it seems, has a way of repeating itself.

The Emerging AI Knowledge Economy

OpenAI, Anthropic, Meta, and others face a growing problem: the internet isn’t infinite-at least not in high-quality, unstructured text. These models need vast, unique corpora to stay competitive. And public-domain books and scraped web forums are no longer enough.

Amidst the growing hunger for high-quality training data, we can expect a surge in new industries and services designed specifically for the AI era.

One emerging area is purpose-built training content-documents, conversations, and workflows crafted not for human consumption, but to teach machines.

Just this month, I’ve had two companies ask for help building tools that plug directly into employee workflows-quietly capturing the content they produce and queuing it up as AI training data. It’s “free money,” they say. The appeal of monetizing work you’re already doing-with almost no additional overhead-is hard to ignore.

Alongside this, knowledge licensing platforms are likely to gain traction. Passive AI training content producers, specialized training content companies, and even individuals with niche skills will need to monetize their expertise.

In the spirit of the classic gold rush strategy-sell the picks and shovels-supporting it all will be a significant secondary market: a critical layer of services, focused on things like data quality, knowledge provenance, usage rights, and chain-of-custody.

Your Experience = AI Fuel

The most valuable training data of tomorrow won’t come from Wikipedia or Reddit. It will come from the daily workflows of financial analysts. It will flow from the decision trees used by senior engineers. It will spring from the nuanced phrasing used by great negotiators, educators, therapists, or chefs.

Capturing and structuring that tacit knowledge turns it into a sellable asset .

Just as “content creator” became a career, so too will the “knowledge synthesizer”-someone who distills deep experience into structured prompts, micro-lessons, and training dialogues for machine learning.

Legalities, Ethics, and Security

As digitized knowledge once again grows in value, so does the potential for theft or misuse. Issues like IP protection, access control, digital watermarking, usage tracking and contractual licensing models will become crucial (startup opportunity, anyone?).

These developments also raise questions. Should creators of training content receive royalties when their data is used to generate outputs? Can you “own” the style or reasoning path of a professional role? What are the rights of creators vs. their employers?

And as we’ve seen before, new sources of valuable data will pique the interest of malicious actors. I haven’t done the research yet, but I’d bet money that marketplaces for stolen AI prompts and training data are already popping up on the dark web.

What I can tell you, from recent client experience: corrupted AI training data as a form of corporate espionage leads to a lot of very ugly fallout.

In addition to general safeguards for AI user interfaces, APIs, MCPs, etc., protecting proprietary AI knowledge is a must. Fine-grained access control (for humans and APIs), provenance tracking, encryption at rest and in motion, access and change auditing should be employed as would be the case with any other valuable data asset.

The good news is that the security controls and design patterns largely exist today. Larger enterprises are repurposing existing data pipelines and repositories to process captured AI training data. The smart ones are already instrumenting excellent security controls in that infrastructure.

Smaller enterprises, startups, and solopreneurs-heads up. This is an area that’s easy to overlook in the fog of day-to-day operations. Take one hour this week to map how your digital knowledge flows-how it’s created, used, stored, and shared. It’s an easy, smart starting point-and a likely wake-up call.

Conclusion: Keep A Weather Eye On The Horizon

We’re entering an era where your daily work-your experience, decisions, and even the language you use-will be harvested as intellectual property. If you’re an expert, a builder, or a thinker, you may be sitting on a goldmine of untapped value. The AI economy isn’t just about models or GPUs. It’s about content-and not just any content, but your content.

Start documenting. Start structuring. Start protecting. Someone is going to stake a claim on your knowledge-and protecting your personal intellectual gold mine is up to you.
